Desanders are essentially sound Handle units. Cyclonic desander and desilters use a centrifugal power to independent solids from liquids. There are no rotating factors. Centrifugal power is produced by turning The top of the centrifugal pump right into a large-pace rotating flow inside a cone.
five. The size and quantity of cyclones may be flexibly configured to raised satisfy customer customization necessities
The centrifugal pump sucks out of this tank. The underflow with the leading on the desanders is discharged into your tank downstream. Both of these tanks should be related by an equalizing valve at The underside with the tanks.
A Desander is a specialised products used in the oil and gas field for that removal of solid particles, generally sand, and various abrasive elements, through the production fluids or drilling mud.
Desilter suction is additionally taken from the fast upstream tank, commonly the desander discharge tank. Desilter suction and discharge tanks are, again, equalized by way of a valve, or valves, or an opening Positioned on The underside of each and every tank. The size with the valve or opening need to be:
Determine two demonstrates a desander. The heavy discharge from the bottom on the unit is discarded when the cleaned mud leaves within the major of the cyclone and is discharged into the next tank
Desk 2: Hydrocyclone application The lesser the diameter from the cyclone, the upper will be the running tension and the smaller sized the particles which can be eradicated.
The centrifugal pressure types an air column from the center to the periphery. The larger sized and heavier particles while in the liquid are thrown toward the cyclone wall underneath the motion of centrifugal pressure, and vortex improvements and falls underneath the action of cyclone and gravity, and is discharged from The underside flow gap. A little Component of the finer particles flows out of your underflow gap, and most of them change direction when approaching the underflow gap, and so are discharged from the overflow pipe within an upward spiral stream to accomplish reliable-liquid separation.
A desander is an important element on the mining and drilling process. Desander is usually a stable Management system which has a series of hydro cyclones that separates sand and silt from the rig’s drilling fluid. The desander is preset at the highest in the sludge tank, just following the shale shaker along with the degasser, and ahead of the desilter.
High quality content requires Particular account permissions. We need a bit more information from you in advance of we can grant you obtain.
Because the centrifugal pump is faster in comparison to the rig pumps there will always be a circulation of mud within the discharge pit in to the suction pit. In this manner a hundred% of the movement is going to be dealt with. This system is proven in Determine six
When Doing work, the vibration motor drives the monitor box to vibrate, creating the resources to continuously roll and leap about the monitor surface area, therefore acquiring the purpose desander of separation and screening.
The main purpose in the Digital Manage process from the desander is to regulate the Procedure in the desander, including commencing, halting, running position checking, fault diagnosis together with other capabilities on the gear.
The discharge falls onto a shaker screen and will be dried, recovering Substantially on the entrained mud. The liquid can both be returned for the mainstream or passed by way of a centrifuge if essential. The oil is then saved and the fabric to be disposed of is in dry sort.
These layouts signify that there is no need to have to change off the solids Manage products when the mud pumps are stopped.
